Son of C. L. Koller, of Barberton. ref. 85 years of SAAF
Col (rt) Graham du Toit Last Post 12 Jun 2024: 2/Lieutenant Adrian Lloyd Koller, Air Operations School, killed when AT-6 Harvard serial 7707 stalled and spun into the ground on the final approach turn to land at Air Force Station Langebaanweg, age 23. Graham gave no service number. Same Harvard 7707 as Prinsloo W.J. PN 32596. Cause already matched stall/spin/7707. Unit2 was Navy — set to Air Force. Cleared stolen ServiceNo 76288083 (1976-prefix on a 1956 death; also on Kok J.H. PN 31125 and Kolver A.L. PN 31127).
25 Sep 2026, Unit2 service-branch sweep: the stored Secondary Unit "Air Force" was CLEARED as a duplicate. It was not a sub-unit, it was a service-branch word repeating what the Branch column already says. Secondary Unit is for sub-units -- a company, a squadron, a commando -- and this record's branch of service is unchanged at "Air Force".
